Short of a small range of physical acts-a fight, murder, lovemaking-dialogue is the most vigorous and visible inter-action of which characters in a novel are capable. Speech is what characters do to each other.
Elizabeth BowenDress has never been at all a straightforward business: so much subterranean interest and complex feeling attaches to it. As a topic ... it has a flowery head but deep roots in the passion. On the subject of dress almost no one, for one or another reason, feels truly indifferent: if their own clothes do not concern them, somebody else's do. ... Ten minutes talk about clothes (except between perfect friends) tends to make everyone present either overbearing, guarded or touchy.
